发明名称 Managing multiple user locks and deletion requests for a digital video recorder
摘要 A method and system for managing multiple user locks and deletion requests on a digital video recorder (DVR) is disclosed. Files associated with the DVR can be protected from deletion by allowing users to lock a recorded file utilizing a number of locking strategies. The recorded file can also be locked by multiple users and the recording can be deleted when the users specifically remove the lock. A simpler interface for each user can be provided to prevent other users from deleting recorded files, which have not yet been viewed. Such an approach allows for an administrative override to prevent users from locking recordings and never unlocking in order to prevent the DVR exhausting disk space.
